Most paleontologists now agree that an asteroid did hit the Earth at approximately the end of the Cretaceous, but there is an ongoing dispute whether the impact was the sole cause of the extinctions. There is evidence that there was an interval of about 7012946728000000000â 300 ka from the impact to the mass extinction.
Dinosaurs became extinct about 65 million years ago at the end of the cretaceous period (see what cretaceous dinosaurs were around at this time). About 70% of all animal life on earth died out. Scientists call it a mass extinction â it wasnât the first mass extinction in earthâs history and it probably wonât be the last! Having existed for 165 million years, why did dinosaurs die out? There are many different theories about why this happened.
